Drill rack for drill press



June 14, 1960 R. HERZOG DRILL RACK FOR DRILL PRESS Filed Sept. 25. 1956 United States Patent Ofiice DRILL RACK FOR DRILL PRESS Ralph Herzog, Box 37, Trail, Oreg. Filed Sept. 25, 1956, Ser. No. 611,845 4 Claims. cram-254 This invention relates to a rack for drills and similar tools, and more particularly to a novel rack or holder which can be mounted directly on a drill press so that drills will be convenient to the place most commonly used.

The primary object of the present invention resides in the provision of a drill holder adapted to be mounted on the column of a drill press so as to make readily available to a machinist drills of varying sizes.

A further object of the invention resides in the provision of a drill holder having means for protecting and shielding the various drills from chips and dirt even though the drill rack may be readily pulled into position for convenient access to the drills.

The construction of this invention features the use of upper and lower cover members which are clampingly secured on the column of a drill press. Journaled on the lower cover member and about the column of the drill press is a sleeve on which the rack is positioned and to which the rack is keyed. The rack itself carries wall portions which cooperate with the upper and lower cover members to form a housing for the drills when the rack is in a closed position.

Still further objects and features of this invention reside in the provision of a drill rack that is simple in construction, which may be conveniently attached to the column of a drill press or a column at a work bench, and in which all sizes of drills can be accommodated whether they are identified by number, letter or fractions and in which the drills can be grouped in order of actual sizes.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this drill holder, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is an elevational view of a drill press shown with the drill holder comprising the present invention installed thereon;

Figure 2 is an enlarged sectional detail view of the drill holder;

Figure 3 is a plan view of the drill rack;

Figure 4 is a vertical sectional view of the rack taken substantially along the plane 44 of Figure 3;

Figure 5 is a plan view of the sleeve with the segmental key;

Figure 6 is a partial elevational view of the sleeve and segmental key; and

Figure 7 is a plan view of the drill holder with a portion broken away to show a part of the rack.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 designates a drill press of conventional design having a table 12, a drill head 14, a motor 16 for driving the drill press and a movable chuck 18 into which drills are adapted to be fitted and which chuck 18 can be carried downwardly so that the drills will engage a workpiece. The drill press 10 includes a standard or column 20 preferably Patented June 14, 1960 2 of cylindrical configuration on which the drill holder comprising the present invention and generally designated by the reference numeral 22 is adapted to be secured. Obviously, the drill holder 22 can be secured on a column stand adjacent a bench, milling machine, lathe or other desired location for holding drills or other similar tools.

The drill holder 22 includes a lower cover member 24 including a clamp arrangement as at 26 having a threaded screw member 28 for use in securing the clamp arrangement 26 about the column 20 of the drill press. The lower cover member 24 has its clamping arrangement 26 provided with a stepped surface as at 30 forming a bearing surface for rotatably receiving a sleeve 32 which may be split as illustrated. The clamp arrangement 26 may be in the form of a split collar formed in a pluralityof pieces which may be threadedly secured together, by means of suitable screws as at 28 or other means for clampingly holding and positioning the lower cover member 24 with respect to the column 20 and thus adjusting the position of the entire drill holder. The lower cover member 24 has an upstanding arcuate wall 25 integral with it at its outer perimeter.

The sleeve 32 is provided with an integrally formed tapering wedge-shaped segmental key 34. This segmental key 34 is in the shape of a segment of a cylinder and has a tapered surface as at 36 forming the wedge shape therefor. The upper edge 37 of the sleeve 32 is in bearing engagement with a stepped surface as at 38 of an upper cover member 40. The upper cover member 40 has an obliquely depending arcuate portion 41 which cooperates with upstanding wall 25. A drill rack 42 is removably mounted on the sleeve 32. The drill rack which can be seen best in Figures 3 and 4 has a partial bore as at 44 and then is recessed as at 46 in a tapering manner as is indicated at 48 for receiving the segmental key 34. Thus, when the drill rack 42 is positioned over the sleeve 32, the segmental key 34 fits into dovetail interlocking relationship within the recess 46. The purpose of key 3 4 is to enable the drill rack to be removed from the sleeve and thus enable the drills to be conveniently carried from one location to another. Alternatively, the sleeve 32 and the drill rack 42 may be formed integrally.

Further, the base portion 52 of the rack is provided with sloping steps 54, 56, 58 and 69 the horizontal surfaces of which are recessed as at 61, 62, 64, 66 and 68 forming sockets for receiving drills for varying sizes. These recesses 61, 62, '64, 66 and 68 can have letters, numbers, or fractions, or other indicia permanently marked thereby.

By means of a screw 70 or other suitable fastener, the clamping arrangement 72 can be used to install the drill holder 22 on the drill press.

The upper cover member 40 cooperates with the lower cover member 24 as well as with the wall portions 49 and 50 to form a housing for the drill rack to deflect dust, chips and other dirt from the drill rack. The cover members 24 and 40 are fixed to the column 26 While the drill rack 42 is rotatable into the closed position as is shown in Figure l and to an open position with the drill rack adjacent and underlying the drill head 14.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
